V2
Decided to do a starfield and do away with the clouds. I worked over a star/neb set up I had used some time ago, which took ideas from several existing starfields such as Moodflows.
Following my same line of reasoning as in making the craters, I replaced the old Perlin fractals, instead used large (but distant) Voronoi billows to create the stars. All piped to a background sphere as luminosity.
Added some likely grunge to the base of the discarded item. The blue power ring must still hold some residual charge and seems to repel dust.
